This invention relates :to improvements in wing windows of the typeemployed'on locm" motives and other moving vehicles for the purpose. ofprotectingftheengineer or othr' as against injury from-dust,dirtandrain, etc., when looking out"through'theqwindow while the vehicle ismoving." v It is well known that eng'nee'rsand fire'-' men in operatingtheir engine, mustfrec uently'stick theirheads out throughithe cabwindowsin orderto obtain a' proper view of the track and train. Andunless they are protected by means of a windshield or-transparent glassmember, their eyes are liable to the purpose of preventing this, it iscustomaryto provide locomotive cabsfwithwing' r windows that can beadjusted so as to, ex- 'tend' perpendicularly: outward so as'toserve.

pane at any time as it is not necessary to remove any screws or boltsand this operation therefore does not require any tools whatever.

In the above description the invention has been described in what isbelieved to be its preferred embodiment, but applicant does not desireto restrict himself to the exact construction shown and described to anygreater 10 extent than necessary in order to avoid the state of theprior art.

Attention is called to the fact that the wing window is so constructedthat it can be used on either side of a cab or vehicle as it issymmetrical with respect to the plane of the window pane. This is animportant feature as it obviates the necessity of carrying right andleft windows in stock whereby a large saving is efiected. a L r 29Having described the invention what I claim as new is:

A wing window for moving vehicles vcomprising, a substantiallyrectangular frame of greater length than width, one of the short endmembers having a slot of somewhat greater length than the width of theopening in the frame, the inner edges of the side members having groovesand the-upper edge of the other end member having a groove, a
